Shimano Deore XT M8100 Series

Lighter than my nx and shifts better,I think. Might just be in my head. Looks cooler too

I can't wait to install this. I'm planning on getting another on for my other bike...

I can't wait to install this crank set. I plan on bying another set for my other bike.

This kit looks awesome, I can't wait to get rid of my 1X9 and install this 1x11 and hit the hills. I plan on buying another set and replacing my 3x9...

Thank you.

I needed a crankset for my 55mm chainline, Thunder mountain had it for a great price, and shipped it faster than the big online shops. I remembered the shop from my time living in AZ. Happy to support them then, happy to do so now.

Like the rubber sleeve on this version’s lever

I ordered a specific not very common crankset, noted it in the order comments, I got a confirmation email right away with a response confirming the specs. Great service.

After 45 years of riding I began to develop numb fingers and painful wrists while riding. Someone suggested much higher bars and these 80mm rise bars have relieved all the pain in my wrists and the numb fingers are gone.

You can’t go wrong with any level of Shimano. They had everything I needed in stock and it shipped and arrived quickly.

Easy to install on my Marlin 7

Went on my Marlin 7 easy.

Came super fast and at a better price than anyone else! Will use Thunder as much as possible.

Needed to replace both brake levers. Manufacturer had a 6 to 8 WEEK backlog. I confirmed with customer service at Thunder Mountain the correct part number and if they had them in stock. Thunder Mountain shipped them the same day I ordered them. Outstanding-Thank You!

Shoes are awesome, typical 510 grip but these definitely do better in the colder weather as they are insulated. Will look forward to doing business with this company again, customer service was top notch and extremely responsive. Went above and beyond for a new customer, thanks again!!
